I will clean custom datasets for ai fine tuning

Messaging beforehand allows us to review a sample of your raw data, check formatting needs, confirm row counts, and provide a free 10-row preview before you spend any money.

We format datasets for OpenAI (GPT-4o, GPT-3.5 Turbo), Anthropic Claude, Meta LLaMA, Mistral, and Hugging Face architectures in .jsonl, .json, or .csv formats.

Our scope includes removing duplicates, stripping corrupted characters, standardizing prompt-response structures, enforcing token length limits, and validating JSONL syntax.

You can upload CSV, Excel, JSON, or text files directly via Fiverr's secure order attachments or share access via Google Drive/Dropbox.

The package price covers all our dataset processing tools. Any external API fine-tuning compute costs on OpenAI or AWS/Azure are paid directly by you to the provider.

Your proprietary data is never shared, retained after project completion, or used for model training. We readily adhere to strict standard NDA practices.

We provide a syntax guarantee. If your upload fails due to schema formatting or JSONL errors, we fix and re-deliver the dataset immediately at zero extra cost.

You will receive production-ready train and validation .jsonl files, an optional clean .csv copy, and a summary breakdown of your dataset tokens and distributions.

Yes, every tier includes revisions to fine-tune instructions, adjust prompt framing, or alter train/validation ratios to match your evaluation feedback.
